libxml2 is prone to multiple integer-overflow vulnerabilities because it fails to properly validate user-supplied input.

Successful exploits may allow the attacker to execute arbitrary code in the context of applications that use the affected library. Failed exploit attempts will likely result in denial-of-service conditions.

Note: This issue was previously discussed in BID 54203 (Google Chrome Prior to 20.0.1132.43 Multiple Security Vulnerabilities), but has been given its own record to better document it.
